All,

The work described below is taking longer than expected. It will probably be around 2:00 this afternoon until we are operational again. I apologize for the delay & will let you know as soon as we are back up and running.

Regards,

Jeff Kuhn

Subject: [Bnc-facility-notice] East Wing Hood Shutdown Wednesday

**********************REMINDER****************************

All hoods in the east wing of the Birck Nanotechnology Center will be shut down at 7:00 am Wednesday morning, 14 November 2012. All hazardous materials - chemical and biological - must be removed from the hoods prior to that time. We hope to have the hoods operational by noon on Wednesday. Please watch for a bnc-facility-notice e-mail and the removal of the signs before using a hood in the east wing.

Hoods in the west wing of the facility will NOT be affected by this work.
